A fault is a series of hooks, nooking into the oppossing plate. One of them giving way, in a small event, gives off its energy partially to the surroundings (the quake) - the rest- stays as additional pressure on another rockformation.

There is a lot of research on people not taking possible disasters serious: https://en.wikipedia.org/wiki/Normalcy_bias

Its understandable, but in the end also just noise for those who do and want to discuss mitigiation strategies or statistics. The urge to conjur up security by repeating doubt mighte be huge, but like all prayer, should be kept to oneself.

i don't really think this is a fair conceptual model for a fault nor for how an earthquake nucleates progresses and then ends. it doesn't really account for plastic deformation, fluids, the interface media (a fault has more than just two rocks touching each other, there is typically some amount of ground up particles, etc that sits at hte interface). there are faults that move aseismically (e.g., the subduction zone in mexico) that do not produce earthquakes at all. faults are a rather complex system that isn't really just hooks connected across an interface. i guess this description could be considered an asperity.
